Ok, so I recently received a Precision 5520 from Dell preinstalled with Ubuntu and I've upgraded to a larger hard drive (Samsung EVO 960 M.2 1TB) and I cannot install ubuntu using the recovery image that is available to me on the Dell website. Oddly, every other distribution that I've attempted to boot from my uefi system works fine, including Mint, Manjaro, Fedora, and openSUSE. Each of these other distros work for the most part but they each have their quirks with my setup, so I thought installing from the actual recovery image would give me the best experience (for instance driver support). Please keep in mind that the computer that came shipped to me also had a M.2 SSD - just a smaller capacity one. For some reason the iso that I download from Dell's official site won't even show up in the boot menu. Please help a frustrated individual. I've been trying to wrap my head around this for over a week now, taking breaks from it and coming back to it, only to hit that wall. I'm typing up this question with my new Precision 5520 (which I absolutely love) with Linux Manjaro installed.) I'd just like to be able to experience Ubuntu with all the Dell drivers with this new 1TB ssd I've installed. Ugh.
